DRINK-MIXER.

Specification of Letters Patent.

Patented Mar. 25, 1913.

Application filed January 11, 1912. Serial No. 670,678.

To all whom it may concern:

Be it known that I, FRANK It. BoNN, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Drink-Mixers, of which the following is a specification.

This invention relates to drink mixers, and has as its object to providea substitute for the ordinary metallic conical mixer. Itis well knownthat such mixers require to be kept scrupulously clean, and that evenwhen this is done, their tin lining is soon eaten away by the acids infruit uices, so as to expose the copper upon which the fruit juices actto form verdigris. Another disadvantage possessed by such a mixer isthat when separated from the mixing glass a greater or less quantity ofthe mixture is spilled, especially if the mixture contains milk or otheringredients liable to foam.

The present invention therefore aims to provide a device for thispurpose, which will not contaminate the drink being mixed, and which maybe manufactured of block tin or other metal not liable to tarnish or beaffected by the ingredients of the drink, at a cost if anything lessthan the cost of the ordinary metallic mixer above referred to.

It is a further aim of the invention to provide a mixer so constructedas to connect in a liquidtight manner the mouths of the two mixingglasses. In this manner, the drink being mixed is in plain view of thecustomer, and comes in contact with but a very small area of metalsurface.

A further advantage possessed by a mixer constructed in accordance withthis invention is that it may be thoroughly cleaned and all partsthereof may be reached, there being no angles or corners in which matterof any sort might lodge.

lVith these and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawing, in which:

Figure l is a vertical transverse sectional view through one form of themixer embodying the present invention; Fig. 2 is a perspective view ofthis form of mixer, and Fig. 3 is a view similar to Fig. 1, illustratinga slight modification of the invention.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

The mixers of both forms of the invention are of annular form and arearranged to receive, from opposite ends, the mouths of two mixingglasses. The mixer as shown in Figs. 1 and 2 is indicated in general bythe reference numeral 1 and is preferably spun or otherwise formed fromblock tin or, other metal not liable to become tarnished or be affectedby acids, and is of annular form and has its inner surface 2transversely convex and perfectly smooth. So far as the actual operationof the mixer is concerned, it may be exteriorly of any desired form,although preferably in order to render it light and cheaper tomanufacture, its exterior surface is transversely concave, as shown inthe said figure. In any event, the inner surface of the mixer isperfectly smooth and unbroken, and is also preferably convex on aregular curve. By giving the interior of the mixer the contour stated,it is formed interiorly of less diameter at its middle than at eitherend.

The mixer shown in Fig. 3 is substantially of the form of that shown inFigs. 1 and 2, the only difference being that While the innor surface ofthe mixer is transversely convex, the said inner surface is not convexon a curve, but on straight lines. In other words, the mixer shown inFig. 3 is in the form of an annular body interiorly flared in thedirection of each end or side.

In using either form of mixer, two mixing glasses are fitted into theopposite ends thereof in the manner illustrated in Figs. 1 and 3, andthe mixer serves to connect them in a liquid tight manner. It will beobserved from the dotted line illustration in Fig. 1 that glasses ofdifferent sizes may be connected by the mixer.

As before stated, the mixer is flared in the direction of each end, andis preferably formed from block tin or some other similar metal which,in addition to the properties before mentioned, is more or less pliable,so that the rims of the mixing glasses will more snugly fit againsttheinner surface of the mixer than if the mixer was formed of some metalnot possessing this property.

As before stated, in using the ordinary metallic conical mixer, when themixer is separated from the mixing glass, more or less of the drinkbeing mixed is liable to be spilled upon the bar, due to the fact thatsuch mixers are ordinarily of the same capacity as the mixing glassitself, and any increase in volume of the drink being mixed due to theformation of foam, will cause the drink to overflow when the mixer isseparated from the glass.

It will furthermore be understood from the foregoing description that,if desired, the device and one mixing tumbler or glass may always beleft engaged and ready for service. Also, it will be apparent thatinasmuch as the device is relatively short, the inserted ends of the twotumblers and the device may be grasped in one hand when mixing a drink.

Having thus described the invention, What is claimed is:

1. A device of the class described comprising an annular body of alength to receive the mouth of a glass or like receptacle in either ofits ends, the said body having its wall of anticlastic form incross-section, the inner surface of the body being continu ously convexfrom end to end of the body.

2. A device of the class described comprising an annular body of alength to re ceive the mouth of a glass or like receptacle in either ofits ends, the said body having its wall of anticlastic form incross-section, the inner surface of the body being continuously convexfrom end to end of the body, the said inner surface of the body beingfree from projections at all points in its area.

In testimony whereof, I aflix my signature in presence of two witnesses.
